I will explain it but lets go through an exercise so you can experience the issue.?
A Legacy engine utilizes the TMCC-2 command set. It has the feature to operate or turn on the Ground lights of an engine.
Can you setup your JMRI to run TMCC and initiate the command to turn on the Ground lights for Engine 65.
Open the TMCC command monitor so you can see the command being sent and post what you send out and how you did it.
In turn I will show you what you should have sent out.
